Guided by the European Adhesive Labeling Association (FINAT) and the North American Adhesive and Packaging and Printing Industry Association (TLMI), working closely with two label material manufacturers and two print processors, PRé as a consultant for two lives Cycle assessment. The goal of these two assessments is to determine the environmental impact of the sticker and to identify environmental hot spots during the life cycle. Both studies were randomly selected from the industry, and the actual use of the region and the chosen printing method were significantly different. According to the data below, the life cycle of the sticker generally includes: acquisition and front-end processing of the label material, manufacturing stage, printing processing, labeling, use, discarding the waste after the label is used, and in the life cycle stage. Necessary transportation.

As can be seen from the data below, the environmental impact of the label's life cycle is different in different processes, but it is mainly concentrated in the supply of label materials and the printing stage. This is mainly due to the input requirements for the production of label materials and the need to consume electricity during printing.

Through research cases, we conclude that during the life cycle of the entire sticker, the following stages account for the environmental impact:

· Label material raw material supply accounted for 40-65%

· Label material production accounts for 2-20%

·Ink supply accounted for 3-15%

·Print processing accounts for 20-40%

· Labeling accounts for 0-3%

Improvement opportunity

1. Recycling or reducing the waste of facial tissue and release paper can greatly reduce the environmental impact of the self-adhesive label life cycle. In summary, we understand that recycled paper and release paper waste will reduce the environmental impact of 5-30% compared to direct incineration. Another opportunity for improvement is by reducing the total amount of raw material input required, such as reducing the thickness of the release paper or reducing paper waste.

2. Recycling now only accounts for a small fraction of the tag value chain. It is important to establish a sense of “recycling good for the environment”. Another opportunity is to reduce the use of electricity during the printing process or to use more sustainable sources of electricity such as solar and wind. These case studies have been applied to the life cycle assessment of the development of a harmonious self-adhesive label industry.
